At Kim Kardashian's True Reflection fragrance launch benefiting Dress for Success Thursday, bystanders were shocked when the star was flour-bombed out on the red carpet.

After posing with her mom Kris Jenner for a few pics, the Keeping Up with the Kardashians star, 31, paused to conduct a few interviews.

That's when Kardashian, who was wearing skin-tight leather pants, a cobalt blue blouse and a black blazer, was doused with an entire bag of flour from head to toe! While onlookers gasped, the reality star was ushered off the red carpet as workers vacuumed the mess.

But rather than call it a night, Kardashian took a cue from Ryan Seacrest (who was the victim of a Sacha Baron Cohen "Dictator" prank at the Oscars in February) and decided to be a good sport about it — and return to the event, cracking jokes about the incident. Meanwhile, the flour-bomber — an as-yet-unidentified woman — was hauled away in a police car, covering up her face.

"This was a Dress for Success charity event so I wanted to come back for all of the women involved," the star told Us Weekly after graciously returning to the red carpet, flour-free. (Once inside the bash, Kardashian and other guests watched the band Caroline Liars perform.)

"But I'm okay! That was insane! I laughed it off and came right back!" she continued. "I took 10 minutes to dust it off and came back to do interviews. When I came back, I just said I asked my makeup artist to bring me powder — and that I didn't think he would bring that much!"
